Title: Decontamination of the scientific literature with the Problematic Paper Screener: Flagging suspect/erroneous/fraudulent papers to crowdsource post-publication reassessments.

Abstract: Imagine reading Fast Fourier Change, Innocent Bayes, and nucleic corrosive* in a scientific paper published in an established journal with Impact Factor from a haute couture publisher such as Elsevier, Wiley, Springer...  Well, we identified more than 11k such problematic papers featuring ‘tortured phrases’ produced by paraphrasing tools to deceive plagiarism detection.  In 2021, this issue affected 3 every 10k papers.  Scammers produce such unreliable papers in bulk to appear hyper productive; they organise citation rings to increase their H-index.
